Mum is Rebel Wilson!

The 42-year-old Pitch Perfect actress shared on Instagram on Monday that she had given birth to a girl through a surrogate.

“Beyond proud to announce the birth of my first child, Royce Lillian, born this past week via surrogate 💗,” she began the heartfelt caption.

“I can’t even describe the love I have for her, she’s a beautiful miracle! I am forever grateful to everyone who has been involved, (you know who you are), this has been years in the making…but particularly wanted to thank my gorgeous surrogate who carried her and birthed her with such grace and care. Thank you for helping me start my own family, it’s an amazing gift. The BEST gift!!”

Added Wilson, “I am ready to give little Roycie all the love imaginable. I am learning quickly…much respect to all the Mums out there! Proud to be in your club. 💗💗💗”

On June 9, Wilson uploaded a cute photo of her and jewelry and fashion designer Ramona Agruma on Instagram, announcing their relationship to the world for the first time.

“I thought I was searching for a Disney Prince … but maybe what I really needed all this time was a Disney Princess 💗🌈💗 #loveislove,” wrote the actress.

“It’s a very serious relationship and they’re super happy together,” an insider said. “It’s been very cool for Rebel’s friends to see her this secure with someone.”

In May, Wilson told PEOPLE that part of her decision to embark on her “year of health” in 2020 was because of her desire to become a mom.

“I was taken aback. I thought, ‘Oh God, this guy’s so rude.’ He was right. I was carrying around a lot of excess weight. It’s almost like I didn’t think of my own needs. I thought of a future child’s needs that really inspired me to get healthier.”

Wilson told the media about being set up with her new partner “through a friend,” though she didn’t reveal who the love interest was at the time.

“We spoke on the phone for weeks before meeting. And that was a really good way to get to know each other,” she said. “It was a bit old-school in that sense — very romantic.”

“I think going through the process of finding more self-worth, I think that what you want in a partner is elevated and so it’s great to have someone who feels like an equal partner and be in a healthy relationship,” added Wilson.
